How does the submerged Wells turbine work?
Best insight from top research papers
The submerged Wells turbine works by converting the pneumatic power of a periodically reversing flow (air or water) stream in an oscillating ocean waving water column into mechanical energy . The turbine is immersed in water instead of air, which enhances its performance by operating with a fluid of higher specific weight . This results in a substantial improvement in turbine efficiency and power production, with a maximum increase of about four times the efficiency in air . Using water as the working fluid also allows for a wider range of operation and delays the stall point . The submerged Wells turbine has a simple structure and aerates water by filling air into it, increasing aeration efficiency and reducing power consumption . This technology can be used in aquiculture devices .

How does the submerged turbine design reduce energy consumption and improve efficiency?5 answersThe submerged turbine designs mentioned in the abstracts reduce energy consumption and improve efficiency in different ways. The submerged turbine aerator achieves this by filling air into the water, which reduces power consumption during aeration and increases aeration efficiency. The floating turbine apparatus minimizes torque loss by having a light hollow body that floats on the water, reducing frictional resistance between turbine blades and water, and preventing water from being scooped up when the blades come out of the water. The developed submerged impulse turbine works as a pressure reducing valve and generates electricity, but its performance for submerged operation is lower due to cavitation caused by water jet issuing from the nozzle. The hydropower turbine in shallow water experiences decreased power coefficient and wave breaking when the free surface is present, but variable pitch can improve power coefficient when the turbine is far from the free surface. The submerged boiler steam turbine uses high-pressure steam generated by the submerged boiler to drive the turbine, achieving energy-saving and recycling of fuel and water.
How does a Pelton turbine work?4 answersA Pelton turbine works by converting the potential energy of water into kinetic energy to generate power. Water is sprayed onto the turbine blades through nozzles, creating high-speed jets that hit the blades and cause the turbine wheel to rotate. The Pelton turbine is known for its efficiency and is suitable for high head and small flow discharge conditions. The torque and power of the turbine are influenced by the valve openings, with varying valve openings resulting in different torque and power outputs. The invention of a Pelton turbine with spiral nozzles improves the design by evenly distributing spiral teeth on the rotating wheel and using concave arc-shaped faces on the upstream faces of the teeth to enhance the rotation. Computational Fluid Dynamics (CFD) analysis is used to predict the flow behavior in Pelton turbines, and a suitable numerical model can be applied to generate a complete performance curve for the turbine. A Pelton turbine nozzle can be produced using additive manufacturing methods, with a subassembly that includes a main housing, servomotor housing, and guide bushing for hydraulic fluid. The Torricelli formula, based on the Bernoulli equation, is used to calculate the jet speed in the injector for energy conversion in Pelton turbines.
What is hydro reation turbine?2 answersA hydro reaction turbine is a type of turbine used to generate electrical power from the flow of water. It consists of a rotor disk with hydrofoil blades, guide vanes, a cylindrical housing, and a generator. The turbine can be deployed underwater, driven by tidal currents, river currents, or wave-driven air, or it can be powered by wind. Another type of hydroelectric turbine system is designed to be located on the seabed and utilizes the tidal flow of water to generate electricity. This system includes a base-mounted turbine and a load bank, which can be selectively connected to dissipate electrical power as heat into the passing water. Additionally, a hydroelectric power generation method involves the use of water turbines arranged in a runner, which are rotated by the natural flow rate of fluids or fluids with a level difference created by a dam.
How can a water turbine generate electricity?4 answersA water turbine can generate electricity through various mechanisms. One approach involves using a generator set connected to a transmission shaft, which is in turn connected to water turbines located in a flow channel. As the water flows through the channel, it causes the turbines to rotate, generating mechanical energy. This mechanical energy is then converted into electrical energy by the generator set, producing electricity. Another method involves using an array of magnets and coils that are radially spaced about an axis. When the first member, which contains the magnets, rotates relative to the second member, which contains the coils, current is induced in the coils, resulting in the generation of electricity. Additionally, a rotary triboelectric nanogenerator can harvest energy from water flows using triboelectric materials. The contact and sliding modes of the nanogenerator, combined with the triboelectrification and electrostatic induction effects, allow for the effective generation of electricity from water movement.
How can a water turbine generate electricity using a water pump?2 answersA water turbine can generate electricity using a water pump through various mechanisms.

Another method is to utilize a hydroelectric generator that uses solar energy to power a piston type pressure water pump for water storage. Additionally, a rotary triboelectric nanogenerator (TENG) can harvest energy from water flows using triboelectric materials, such as polytetrafluoroethylene (PTFE) and Nylon 6.6. Another invention involves a water turbine for water power generation that utilizes a vortex formed in supplied water to generate rotational forces. Furthermore, a water turbine pump can be used to pump water and generate electricity by connecting the pump shaft with a generator, allowing water energy to directly drive the generator. These different approaches demonstrate the various ways in which water turbines can generate electricity using water pumps.
